Abstract
A rotary cutter lifting apparatus comprising a table plate having an opening and an upper surface, a carriage disposed beneath the table plate and adapted for supporting the rotary cutter, and an adjustment mechanism positioned entirely below the table plate upper surface and operable through the opening. A method of operating a rotary cutter lifting apparatus comprising the steps of positioning the rotary cutter lifting apparatus having a carriage and an adjustment mechanism entirely below a table plate upper surface having an opening, and operating the adjustment mechanism through the opening.
Claims20
A rotary cutter lifting apparatus comprising:
- a table plate having an upper surface, a lower surface and an opening extending from the upper surface to the lower surface;
- a carriage disposed beneath the table plate and adapted for supporting the rotary cutter;
- an adjustment mechanism positioned entirely below the table plate upper surface;
- a lift wheel of the adjustment mechanism which is rotatable about a lift wheel axis and has a circular outer surface which is concentric about the lift wheel axis and defines a lift wheel outer diameter;
- a first position of the lift wheel in which a first portion of the circular outer surface is adjacent the opening and a second portion of the circular outer perimeter is lower than the first portion and lower than the table plate lower surface;
- wherein the lift wheel is rotatable from above via the opening by engagement with the circular outer surface;
- and
- rotation of the lift wheel causes vertical movement of the carriage.
A rotary cutter lifting apparatus comprising:
- a table plate having an opening and an upper surface;
- a carriage disposed beneath the table plate and adapted for supporting the rotary cutter;
- and
- an adjustment mechanism positioned entirely below the table plate upper surface and operable through the opening;
- in which the adjustment mechanism further comprises:
- an axle;
- and
- a lift wheel mounted on the axle whereby rotation of the lift wheel causes rotation of the axle and movement of the carriage;
- and
- wherein the axle further comprises a longitudinal axis which is perpendicular to the direction of movement of the carriage.
A method of operating a rotary cutter lifting apparatus comprising the steps of:
- positioning the rotary cutter lifting apparatus having a carriage and an adjustment mechanism entirely below a table plate upper surface having an opening;
- and,
- operating the adjustment mechanism through the opening by inserting a finger from above the opening into the opening to engage and move the adjustment mechanism with the finger below the table plate upper surface such that moving the adjustment mechanism with the finger causes vertical movement of the carriage.
